Hi i have a Technics 200 watt receiver/amplifier and 6 disc (cartridge) CD player connected to my Sony speakers. The receiver/amplifier only had a connection for 2 speakers, and i have 4, so I wired two speakers on each connector. the prob is there is a loud humming from speakers when i have the CD player on..is there a solution for this?
Yes, The humming is always there you just can hear it better when the cd is playing. The humming is caused by the electrical system in your car. There is an inline filter you can buy and insert it between the car's power source and the head unit. I had a head unit I bought that was absolutly terrible until I installed that filter. Also if you did a do it yourself job on your amp wiring it is usually best practice to run your RCA cables on the opposite side of the car as your power cable. You can also purchase shielded spark plug wires which is a source of noise usually of a different kind tho. First make sure you have a good ground. This means that you have grounded your amp to bare metal not painted metal. If that didn't work put in the inline filter on the head deck as they are only $20 available at radioshack. If that doesn't work, go back an wire your car right this time and put the power and RCA on opposite sides of the car. If you still have that hum it may be the spark plug wires but that sounds more like static than hum. You have a text book case of alternator hum... Hack
